promptql-api-sdk 0.2.0

Python SDK for PromptQL Natural Language API

PromptQL Natural Language API SDK for Python

A Python SDK for interacting with the PromptQL Natural Language API.

Installation

pip install promptql-api-sdk

Or with Poetry:

poetry add promptql-api-sdk

Features

• Full support for the PromptQL Natural Language API (v1 and v2)
• Type-safe interface with Pydantic models
• Support for streaming responses
• Conversation management
• Support for all LLM providers (Hasura, Anthropic, OpenAI)
• Support for build-based configuration (v2 API)

Quick Start

v2 API (Recommended)

The v2 API uses build-based configuration and is the recommended approach:

from promptql_api_sdk import PromptQLClient

# Initialize the client with build version
client = PromptQLClient(
    api_key="your-promptql-api-key",
    build_version="your-build-version",  # or use build_id=UUID("your-build-id")
    timezone="America/Los_Angeles",
)

# Send a simple query
response = client.query("What is the average temperature in San Francisco?")
print(response.assistant_actions[0].message)

# Use streaming for real-time responses
for chunk in client.query("Tell me about the weather in New York", stream=True):
    if hasattr(chunk, "message") and chunk.message:
        print(chunk.message, end="", flush=True)

Note: To use applied build, do not specify build_version or build_id.

client = PromptQLClient(
    api_key="your-promptql-api-key",
    timezone="America/Los_Angeles",
)

v1 API (Legacy)

The v1 API requires DDN /v1/sql URL and explicit LLM provider configuration:

from promptql_api_sdk import PromptQLClient
from promptql_api_sdk.types.models import HasuraLLMProvider

# Initialize the client
client = PromptQLClient(
    api_key="your-promptql-api-key",
    ddn_url="your-ddn-url/v1/sql",
    llm_provider=HasuraLLMProvider(), # Required for v1 API
    timezone="America/Los_Angeles",
)

# Send a simple query
response = client.query("What is the average temperature in San Francisco?")
print(response.assistant_actions[0].message)

Private DDN

If you are using a private DDN, you need to provide the base URL for the PromptQL API:

client = PromptQLClient(
    api_key="your-promptql-api-key",
    build_version="your-build-version",
    timezone="America/Los_Angeles",
    api_base_url="https://promptql.fqdn.hasura.app/api",
)

Note: The api_base_url should not include the /query endpoint.

For more details refer to the PromptQL API Endpoint documentation.

Conversation Management

The SDK provides a Conversation class to help manage multi-turn conversations:

# Create a conversation
conversation = client.create_conversation(
    system_instructions="You are a helpful assistant that provides weather information."
    # Note: system_instructions are ignored in v2 API as they come from build's PromptQL config
)

# Send messages in the conversation
response = conversation.send_message("What's the weather like in London?")
print(response.message)

# Send a follow-up message
response = conversation.send_message("How about tomorrow?")
print(response.message)

# Get all artifacts created during the conversation
artifacts = conversation.get_artifacts()

LLM Provider Configuration (v1 API only)

The SDK supports multiple LLM providers for v1 API:

from promptql_api_sdk.types.models import HasuraLLMProvider, AnthropicLLMProvider, OpenAILLMProvider

# Hasura (default)
hasura_provider = HasuraLLMProvider()

# Anthropic
anthropic_provider = AnthropicLLMProvider(api_key="your-anthropic-api-key")

# OpenAI
openai_provider = OpenAILLMProvider(api_key="your-openai-api-key")

# Use with the client (v1 API only)
client = PromptQLClient(
    api_key="your-promptql-api-key",
    ddn_url="your-ddn-url/v1/sql",
    llm_provider=anthropic_provider,
)

Note: In v2 API, LLM configuration is managed through the DDN build's PromptQL settings.

API Version Differences

v2 API (Recommended)

• Uses build-based configuration (build_version or build_id) (optional, uses applied build if not specified)
• LLM configuration and system instructions come from build's PromptQL config

v1 API (Legacy)

• Uses direct DDN /v1/sql URL
• Requires explicit LLM provider configuration
• System instructions specified in requests

Error Handling

from promptql_api_sdk import PromptQLClient
from promptql_api_sdk.exceptions import PromptQLAPIError

client = PromptQLClient(...)

try:
    response = client.query("What is the weather like?")
except PromptQLAPIError as e:
    print(f"API Error: {e}")
